derstood, for a rounded edge might be construed to mean round instead of 
sharp, applying the term not to curvature of the sides. But on further con- 
sideration, it seems to me that the adverb wtrinque, applied in this case, will 
do as well as coining a new word. Thorace utrinque deflexo lateribus rotundatis, 
or vice versa, utringue rotundato, lateribus deflexis, seems to me quite clear of 
objection. What do you think? I don’t see that we have any term for the 
point of meeting of two joints. With respect to tibia and femur, geniculus 
will do very well; the other end of tibia and tarsus, if necessary to be noticed, 
would with equal propriety be denominated calz or heel. With respect to the 
point of meeting of two joints of antenne or palpi, no term strikes me that would 
be proper: can you think of one, or would one be necessary? You observe 
we have no term for ligula, Fabr. We agreed to call this part lingua. If a 
diminutive for lingua is to be used, it might as well be used for all tongues of 
insects that are properly such. I think the same name should be given to the 
same part in all orders; in fact, in use the ligula comes nearer to the tongue 
of animals than the sucker-tongues. Palpi.—I have no objection to employ 
this as English instead of feelers. 
“ Ovate and obovate. — With respect to the abdomen of Coleoptera, I look 
upon them to be ovate when broadest towards the thorax, and obovate when 
broadest towards the anus; and so with respect to the whole insect. With 
respect to the thorax, Linné seems to reverse this plan, calling the thorax in 
Curabus, obcordatus. His idea of ovatus is plain, from his calling Spheridium 
scarabaoides, ovatus. With respect to the head, Fabricius makes it ovate when 
it is broadest at the thorax in the Staphylini of the family of linearis. The 
thorax of Curculio Palmarum, Linné makes ovatus; Curculio Germanus is cor- 
pore ovato. So that, as it should seem, the ovate body is broadest towards the 
head; the ovate head is broadest towards the thorax; the ovate thorax is 
broadest towards the elytra ; but the oyate elytra or abdomen are broadest to- 
wards the thorax: the reason of this seems to be, that the apex of the elytra or 
abdomen must be reckoned at the anus;,but one would think the apex of the 
whole body should not be reckoned as there. 
“ Hypochondria, — Waving no anatomical books, I rely on the correctness of 
your statement with respect to its station. I thought the second cavity of the 
abdomen, which is analogous to our prospectus, was the region of the Hypo- 
chondria, in which case the term would be proper. I have no objection (stating 
our reasons for receding from Linné), to adopting Paraplexra. 
« Levis et equatus, &c.—We have a term (levigatus) which seems to answer 
for this purpose, ‘ very smooth without elevations or depressions,’ but somehoy7 
or other we have not got levis. I see in the book in which I arranged Linné’s 
terms alphabetically, we have ‘/evis, smooth, without elevations,’ and ‘levigatus, 
smooth, without depressions.’ I suppose we then thought one term sufficient. 
Linné uses the term @qualis for your @quatus, it should seem, under Tenebrio 
gigas and mortisagus, He appears to have wanted a term of this sort when he 
describes Teneb. levigatus, and latipes, for he says, ‘levis, elytris levibus, to 
distinguish them from 7’, variabilis, which is levis, elytris elevato-punctatis. If 
we use levis and levigatus, the former should signify the absence of sirie, chan-~ 
nels, foveole, or fossule, and similar kinds of sculpture; and the latter, which 
implies a more intense degree, should denote the absence of points, granules, 
or any roughnesses of surface. It would sound well to say levis, elyiris 
levigatis. But, perhaps, you will think three terms necessary, one for the ab- 
sence of smaller inequalities, another for the absence of larger, and a third for 
the absence of all inequalities; then it would be @guatus or equalis, without 
larger elevations or depressions ; /evis, without smaller elevations or depres~ 
sions ; /evigatus, without any elevations or depressions,
